Abstract :
The development of a 2 MW, CW, 170 GHz coaxial cavity gyrotron at Forschungszentrum Karlsruhe (FZK) is in progress in cooperation with several European research institutions. The gyrotron is foreseen as a source for heating, current drive and stabilization of plasmas in the International Thermonuclear Experimental Reactor (ITER). Tests with a first industrial prototype started recently at CRPP Lausanne. The design of critical components, especially the electron gun, cavity and quasi-optical (q.o.) RF-output system has been verified at FZK in tests with a short pulse gyrotron, the so called pre-prototype. Results of the experimental investigation at FZK was presented and discussed.
